Getting Started with DataGrid and another datagrid form

[Sannyasin Brahmanathaswami]

Yay! I made my first form.

Now for questions *not* covered by the lessons.

1) Is the graphic "Background" a special object? In Navigator I opened
stack

"Data Grid Temple 33333333333"
 
directly  editing the group "Row Template". I set background graphic to
roundedRectangle, corners set 20px, and applied a linear gradiant with
nice colors. I saved the stack.

But the graphic did not change?  I *can* adjust its rect, and the
rounded corners show (appears on hilite, the it is tranparent otherwise)
and that sticks, but not linear gradient?

2) How do I make the datagrid transparent (opacity to 0).  So that
between the rows there is a margin which shows the background of the
card coming through.
